SpamAssassin is a mail filter used to identify Spam.
It uses a number of tests to determine if a piece of email is legitimate or Spam. If it
is determined to be Spam, it can either sorted to a separate mail folder
for further analysis, thrown away, or delivered back to your inbox marked
as Spam. There are also a number of ways you can fine tune your filtering
to make sure legitimate email is let through and email that you don't
want gets blocked.

One way Spam Assassin determines Spam is by Hits. Hits are a
point scale used to determine if a piece of mail is legitimate or not.
For example, if a message mentions something about "viagra" it will get
a point. If it written in all CAPS it may get another point. If the
amount of combined points a message gets reaches or exceeds the point
threshold, it gets marked as Spam.

Sometime you may have email addresses that you know would never send
you spam, so you can place them in a whitelist to always be allowed
through. You may have an email address or domain that always sends you
messages that you do not want to receive. These ones can be placed on a
blacklist and will always be treated as Spam.

In the "Mail" section, click on the button that's labeled "SpamAssassin Mail Filter"

Click on "Turn Spam Assassin ON"

Choose one of the following:

Permanently Delete - this will delete all messages marked as Spam. This is not recommended to start because if you have legitimate email that is blocked by accident, it cannot be recovered. If you are comfortable with the way the spam filter works and is configured, use this mode to delete all spam.

Deliver normally with SPAM tags - This will deliver Spam normally to your mail box but will mark it as SPAM in the subject line and tell you in the body of the message why the message is marked as Spam. You can then sort it with your email program. Here are instructions on how to do that with Outlook.

Save to mail file - This is the default setting. This will save Spam to a separate folder where you can check the messages in the "Spam Mail" section of "Spamassassin Mail Filter" on webadmin. By default, it is set to save to "mail/spam" on your account.

Click on the button that says "Turn Spam Assassin ON

Checking Your "Spam Mail" folder

If you've chosen the option to "save to mail file", it is stored on your account and can be
reviewed via the WebAdmin control panel in "Spam Mail"

IMPORTANT: If you choose to save your mail to a Spam folder, you
must empty out your Spam Folder periodically. The Spam that gets
collected counts against your disc quota and will build up if is not
cleaned out. If you go over your disc quota, this will cause problems and
may cause new mail to NOT be delivered to your account.

In the "Mail" section, click on the button that's labeled "SpamAssassin Mail Filter"

Click on "Spam Mail"

From here, you have a few options of what to with the Spam. You can view the message by clicking on the title or you
can apply an action to one or more of the messages

To apply and action: First, you select all of the messages that you want to perform an
action on by selecting the box next to the message, or by selecting all
of the messages by clicking on "Select All".

Actions

Move to Inbox - This will move selected emails back into your inbox after removing the Spam Assassin tags

Move to Inbox and Allow Sender - This does the same as the above option but adds the senders email to your "whitelist" so all future emails will not be marked as Spam

Delete - This will delete the selected emails

Delete and Report to Razor - This does the same as the above option but reports it to the Razor Spam database. NOTE: This is an advanced option. Don't choose this option unless you know what you are doing.

Fine Tuning Spam Assassin

There are a number of ways to configure Spam Assassin, but the
average user usually only needs to set a few of them for regular use.
Most important of these is the threshold for Hits.
Turning the threshold up allows more Spam to go through, turning it down
reduces the amount of Spam going through but may increase the amount of
legitimate mail accidentally getting marked as Spam. You can adjust this to your liking

In the "Mail" section, click on the button that's labeled "SpamAssassin Mail Filter"

Click on "Spam Classification"

Next to "Hits above which a message is considered spam" click on the second option and set your desired Hit threshold in the box next to it (Ex. 7, 5.75, 4.5, etc)

Click on the "Save" button

There are other options on this page that you can change but these settings are for experts only. Please use caution when adjusting these settings

Setting up Black Lists and White Lists

You may have email addresses that you know would never send
you spam, so you can place them in a Whitelist to always be allowed
through. You may have an email address or domain that always sends you
messages that you do not want to receive. These ones can be placed on a
Blacklist and will always be treated as Spam.
